Reg Braithwaite has a very strong case for being more open-minded in your programming research/learning.
Having said that, this is probably the difference between the Myers-Briggs INTP and INTJ subtypes. INTJs (which is very common amongst programmers) are prone to judging and rejecting information that they disagree with.  INTPs less so.
Having said that, I’ve certainly made this mistake on more than one occasion (and quite possibly blogged about it as well). Â But now that I’m thinking about it, I suspect I’ll make it less often.
